output variable to read from

width, height

Must be a valid CSS unit (like '100%', '400px', 'auto') or a number, which will be coerced to a string and have 'px' appended.

expr

Is expr a quoted expression (with quote())? This is useful if you want to save an expression in a variable.

Value

Examples

if (require("shiny") && interactive()) {
ui <- fluidPage(
  visual_diff_output("diff")
)

server <- function(input, output, session) {
  path1 <- tempfile()
  path2 <- tempfile()
  writeLines(letters, path1)
  writeLines(letters[-13], path2)

  output$diff <- visual_diff_render(visual_diff(path1, path2))
}

shinyApp(ui, server)
